Where did u all run ur amp power wires through the firewall? im thinking of running it below the bulk connector from the engine bay to the cab. seems easy access from inside the cab to drill and i can still get to it in the engine bay. i also seen the groumet for the throttle cable but id rather not put it through there.

i ran mine under the truck its 0gauge so threw the fw would have been tough, in the ext cab there is grommets in the rear under the carpet for water drainage i assume. its zip tied to the frame then up to the body.

A few years ago, I needed to route a power wire and a couple of alarm wires through the firewall. Holes were drilled above the factory bulkhead connector next to the brake booster and grommets installed. While I was at it, I added some extra holes/grommets in various sizes for future mods and plugged them with bolts. These have proven to be very useful over the past couple of years and I now have wires and a vac line running through all 5 of the holes.

To make room for the drill motor, the underhood electrical distribution box was temporarily unbolted and moved over. There is a large wire bundle on the interior side that may need to be repositioned out of harm's way while drilling.

im gunna go with the place i wanted which is where bob drilled his. i do like those firewall grouments...better than the regular round ones...i think i will even drill extra holes for other goodies :-D

thats how the previous owner had mine, i guess he never went wheeling because the first time i did it came loose and fryed on the exhaust manifold, i just put a grommet in an existing hole under the gas pedal area. fit 4gauge perfectly.
